What does fundal height measurement equal until week 32?

Until week 32, fundal height measurement is used primarily to provide an approximation of the gestational age in weeks. This correlation is based on the understanding that, up to this point in pregnancy, the growth of the uterus correlates closely with the development of the fetus. Specifically, the fundal height in centimeters typically aligns with the number of weeks of gestation when measured from the pubic symphysis to the top of the uterus.

This measurement can help healthcare providers assess fetal growth and development, ensuring that it is progressing normally. If the fundal height does not match the expected gestational age, it may lead to further investigations into the health of the fetus or the pregnancy.

The other options do not accurately describe what fundal height reflects at this stage in pregnancy. While weight, estimated fetal size, and expected delivery date may be pertinent in a broader context of pregnancy monitoring, they do not serve as direct indicators of fundal height measurement before week 32 as gestational age does.
